2 Claims.

This invention relates to radio apparatus, and more. particularly to the construction of the aerial or lead in wire thereof, the primary object of the invention being to provide novel means for eliminating static.

An important object of the invention is to provide a device of this character which may be readily and easily connected with the usual aerial, eliminating the necessity of making changes in the aerial construction to install the device.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a view illustrating a static eliminating apparatus constructed in accordance with the invention, as connected with the aerial of a receiving set.

Figure 2 is an enlarged view illustrating the containers or basins forming a part of the static eliminator.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Referring to the drawings in detail, the reference character 5 designates the aerial of a receiving set, which is constructed in the usual and well known manner, the same being insulated from the supporting posts 6 by means of the insulators '7.

The reference character 8 designates a wire that connects with the aerial wire 5, and extends downwardly, passing through the tube 9 embedded in the ground surface, where the wire 8 is insulated from the ground. This wire 8 extends into the receptacles 10, where portions of the wire are formed into coils 11, the wire passing through the receptacles Where it is connected with the aerial wire 5, at 12, or at the opposite end of the aerial Wire 5. These receptacles 10 are constructed of porcelain, and are provided with covers 13 which are sealed when positioned, to exclude moisture and prevent dampness from entering the coils. I

The receptacles are filled with pulverized iron ore which completely surrounds the coils so that the electric currents passing through the wire and coils will be absorbed, through the mineral contained in the receptacles.

The lead in wire leading to the radio set, is indicated by the reference character 14, and connects with the wire 8, at a point between the receptacles 10 so that the electric current must pass through the coils 11 before passing to the lead in wire.

Due to the foregoing construction, it will be found that electric currents that cause static, are absorbed by the pulverized iron ore, to the end that the radio reception is smooth and regular.

I claim:

1. The combination with the lead-in wire and aerial wire of a radio receiving set, of a static eliminator comprising receptacles constructed of 7 insulating material, embedded in the ground surface, a pipe establishing communication between the receptacles, pipes leading from the receptacles and having upturned ends extended through the ground surface, a wire having its ends connected to the aerial near the ends of the aerial, the intermediate portion of the wire passing through the pipes and through the receptacles, that portion of the last mentioned wire disposed within the receptacles, being formed into coils, conductive 30 material surrounding the coils, a pipe connected with the first mentioned pipe at a point between the receptacles, and extending through the ground surface, and said lead-in wire passing through the last mentioned pipe and having con- 5 nection with the wire connected with the aerial wire at a point between the receptacles.

2. The combination with the lead-in wire and aerial wire of a radio receiving set, of a static eliminator comprising a wire having its ends connected to the aerial wire, adjacent to the ends of the aerial wire, a portion of the last mentioned wire being embedded in the ground surface and insulated from the ground surface, said wire being formed into coils, receptacles constructed of insulating material, embedded in the ground surface and in which the coils are positioned, conductive material within the receptacles and surrounding the coils, and a lead-in wire leading to a radio receiving set, the lead-in wire being connected with the wire connected with the aerial, at a point between the receptacles.
